Abstract: In the radar system, DBF (digital beam forming) system usually adopts FPGA+DSP, Aimed at the FPGA in DBF system, based on UVM (Universal Verification Methodology), we established a Universal Verification Platform for DBF FPGA model, to enhance the verification platform reusability and verification coverage ratio, the verification platform can improve verification efficiency.Finally, based on the universal verification platform, by means of add test stimulations and reference model to verify an fractional delay filter model in DBF system.
